\n
Engineered specifically for B2B projects operating in frigid outdoor conditions, the BAKTH\u2011HL18650V\u20112P\u20113J lithium-ion battery pack adopts a 2-parallel 18650 low-temperature cell configuration, delivering steady 3.6V output with 5.6Ah rated capacity and 20.16Wh energy storage. The standout advantage of this model lies in its exceptional cold resistance, maintaining dependable discharge performance even down to -40\u2103, solving the common power attenuation problem for field equipment used in alpine, polar and cold-region monitoring applications.<\/div>\n<\/div>\n
\n
This battery pack is designed with 0.5C max charge current, max charging voltage of 4.2V and 2.0V discharge cut-off voltage. The low charging rate minimizes thermal stress on cells during cycling, extending the service life for your end products. Its integrated BMS continuously monitors cell voltage and temperature, implementing automatic cut-off protection against over-charge, over-discharge, over-current and short-circuit hazards. Whether deployed in freezing winter field sites or high-temperature enclosed equipment housings, this battery retains stable power output across the full -40\u2103 ~ 60\u2103 spectrum.<\/div>\n<\/div>\n
\n
All units pass rigorous third-party compliance testing. Complete certification packages including IEC62133 safety report, UN38.3 transportation document and RoHS compliance certificate can be supplied with bulk orders. These official certification files greatly simplify customs clearance and product compliance registration for your finished instruments exported to Europe, North America and global industrial markets.<\/div>\n<\/div>\n
\n
The ultra-miniature footprint is another key selling point. Its maximum dimension is 70mm \u00d7 38mm \u00d7 20mm, and the total weight is only 100g. The slim compact form factor fits neatly inside compact handheld devices and small sensor enclosures with limited internal installation room. Our engineering team provides flexible customization solutions including wire length adjustment, connector replacement and private label printing, so you can match the battery to your hardware design without heavy rework.<\/div>\n<\/div>\n
\n
We provide consistent bulk supply for worldwide B2B manufacturers. Three branding options are available: standard BAKTH marked packs, neutral unbranded batteries, and fully customized OEM packs printed with your corporate logo. Prior to shipment, every batch undergoes multi-stage QC workflows: low-temperature performance screening, internal resistance sorting, voltage balancing and cycle sampling testing. Strict quality control guarantees batch consistency for your mass production.<\/div>\n<\/div>\n
